[GIT,PULL] arm64 updates for 6.4

Hi Linus, Please pull this round of arm64 updates for 6.4. I've summarised the topic branches in the tag commit, but the bulk of the code changes here stem from a rework of the PMU driver so that PMUv3 hardware can be driven on both 32-bit and 64-bit CPUs. From a logistical perspective, we've got a couple of interesting cross-tree interations: (1) We have a shared tracing branch with Steve (pulled from his 'trace-direct-v6.3-rc3' tag) so that the arm64 support for direct calls can be implemented on top. This then ends up conflicting with a fix that landed after -rc3 in 2a2d8c51defb ("ftrace: Fix issue that 'direct->addr' not restored in modify_ftrace_direct()"). The code changed by the fix is removed by the tag from Steve in 8788ca164eba ("ftrace: Remove the legacy _ftrace_direct API") and the only part that needs fixing up is the definition of 'MULTI_FLAGS' to use 'FTRACE_OPS_FL_SAVE_ARGS' instead of 'FTRACE_OPS_FL_SAVE_REGS'. (2) Moving the PMUv3 driver out into drivers/perf/ triggered a latent probe-ordering bug with (p)KVM, so we're carrying a fix for that here with Marc's Ack. Cheers, Will --->8 The following changes since commit e8d018dd0257f744ca50a729e3d042cf2ec9da65: Linux 6.3-rc3 (2023-03-19 13:27:55 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-upstream for you to fetch changes up to eeb3557cc188e42ae7f7bef2d6dc5bf0e078412e: Merge branch 'for-next/sysreg' into for-next/core (2023-04-20 18:03:07 +0100) ---------------------------------------------------------------- arm64 updates for 6.4 ACPI: * Improve error reporting when failing to manage SDEI on AGDI device removal Assembly routines: * Improve register constraints so that the compiler can make use of the zero register instead of moving an immediate #0 into a GPR * Allow the compiler to allocate the registers used for CAS instructions CPU features and system registers: * Cleanups to the way in which CPU features are identified from the ID register fields * Extend system register definition generation to handle Enum types when defining shared register fields * Generate definitions for new _EL2 registers and add new fields for ID_AA64PFR1_EL1 * Allow SVE to be disabled separately from SME on the kernel command-line Tracing: * Support for "direct calls" in ftrace, which enables BPF tracing for arm64 Kdump: * Don't bother unmapping the crashkernel from the linear mapping, which then allows us to use huge (block) mappings and reduce TLB pressure when a crashkernel is loaded. Memory management: * Try again to remove data cache invalidation from the coherent DMA allocation path * Simplify the fixmap code by mapping at page granularity * Allow the kfence pool to be allocated early, preventing the rest of the linear mapping from being forced to page granularity Perf and PMU: * Move CPU PMU code out to drivers/perf/ where it can be reused by the 32-bit ARM architecture when running on ARMv8 CPUs * Fix race between CPU PMU probing and pKVM host de-privilege * Add support for Apple M2 CPU PMU * Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event dynamically, depending on what the CPU actually supports * Minor fixes and cleanups to system PMU drivers Stack tracing: * Use the XPACLRI instruction to strip PAC from pointers, rather than rolling our own function in C * Remove redundant PAC removal for toolchains that handle this in their builtins * Make backtracing more resilient in the face of instrumentation Miscellaneous: * Fix single-step with KGDB * Remove harmless warning when 'nokaslr' is passed on the kernel command-line * Minor fixes and cleanups across the board ---------------------------------------------------------------- Baoquan
